I have a workbook that will be used for public consumption and must not be allowed to be edited. Permission to view this workbook must end at a specific date.
In the professional version of excel, we can choose to "do not distribute" and to set an expiration date for the workbook. This seems to work well, but since I am fairly new to the use of these settings, I would like to know if anybody is aware of ways in which these settings could be hacked.
The nature of the material is highly sensitive, and it would be very helpful to know if I need to consider some other type of encryption. Thanks a lot.
